title: Posture, spontaneous movements, and behavioural state organisation in infants affected by brain malformations.
abstract: Posture, quantity of spontaneous movement patterns, quality of general movements (GMs), and behavioural state organisation were studied in nine infants affected by documented brain malformations. A single 1 h video recording of five infants and two or more serial video recordings of another four infants were performed after birth. The graphic representation of single movement patterns (actogram) and of behavioural states of one video recording was performed in eight out of nine infants. The quality of GMs was assessed according to Prechtl's method in all video recordings. All nine infants showed a less variable posture than normal newborn infants and an unusual resting posture was detected in seven infants. Poor behavioural state organisation without sleep cycles was common to the nine infants and excessive wakefulness was observed in six infants. As for the quantity of single movement patterns, six infants lacked one or two movement patterns normally present in healthy newborn infants. An abnormal quality of GMs was noted in all nine infants and distinct motor abnormalities were observed in single infants. A monotonous and sometimes stereotyped sequence of different body parts involved in the movement (i.e. poor repertoire GMs) was common to all infants. In the four infants of whom two or more video recordings were available, initial poor repertoire GMs were followed by a further deterioration in movement quality. No relationship was found between the quantity of defective brain tissue, lack of a specific part of the brain, type and severity of GM and posture abnormalities.
